Abstract

Abstract: According to the requirements of quick starting of the peak shaving power plant and the requirement of fire protection and explosion prevention for the gasfired unit, combining with the practical situation of the unit, some technical data, such as the practical space volume occupied by the gas turbine and the heat recovery boiler, the air flow for purging of the gas turbine at the purging rotate speed, the purging air replacement ratio and so on, were analyzed. The time needed for gas turbine purging was reconfirmed. According to the final calculation result, the gas turbine purging time was shortened from 15min to 10min. The starting time of the unit was shortened, and the startup speed of the peak shaving power plant was improved.
